Lots of people who are moving from MySQL often miss the sample database Sakila. MySQL has very popular database called Sakila. In this article we will go over various sample databases for PostgreSQL databases. This is when the user needs a sample database. It is quite easy to set up sandbox environment but it is not easy to setup a real world scenario in a database. It is a secure environment where users can try out various new features, learnings and technology experiments in a safe zone without using or taking up production server space or bandwidth. A sandbox environment is the place where there are scenarios like the real world but no real world data. You are now connected to database "db1" as user "postgres".If a developer is attempting to learn a new process or test some code, it’s best to utilize a test environment such as a sandbox rather than the production server. NOTE: In the above example, the database ‘db1’ will be created with the use of -C option, and -d is to just specify the existing database for connection. pg_restore -Fd -C -d postgres -p 5432 -U postgres /tmp/backupdirformat You can either drop the existing database or restore on another port. pg_restore -Fd -l /tmp/backupdirformatģ682 0 16385 TABLE DATA public t1 postgresģ683 0 16388 TABLE DATA public t2 postgres The -l command will list the table of contents, which you can use to find the db name. To restore the directory format, tell pg_restore to create the named database for restoring. pg_dump -Fd -h localhost -p 5432 -U postgres db1 -f /tmp/backupdirformat To dump a database into directory format, use the following command: $. pg_restore -Fc -d restoredb2 -U postgres /tmp/compressedformatdump.dump To restore the compressed format dump: $. NOTE: You can use the -Z option for compression level. pg_dump -Fc -h localhost -p 5432 -U postgres db1 -f /tmp/compressedformatdump.dump To dump a database into compressed format, use the following command: $. ![]() You are now connected to database "restoredb1" as user "postgres". pg_restore -Ft -d restoredb1 -U postgres /tmp/tarformatdump.tarĪfter restoring, you can cross-validate the restored database objects. pg_dump -h localhost -p 5432 -U postgres db1 -Ft -f /tmp/tarformatdump.tar To dump a database into tar format, use the following command: $. The default format for pg_dump is plain text. In the examples below, we will see how to take dump in various formats like tar, custom, and directory format: -F, -format=c|d|t output file format (custom, directory, tar) psql -f /tmp/plaintxtdump.sql -d restoredb -p 5432 -U postgres To restore a plain text dump the following command can be used: $. Since the above dump is a plain text dump, it can be restored using psql. pg_dump -h localhost -p 5432 -U postgres db1 -f /tmp/plaintxtdump.sql pg_dump -versionīackup a single database with its schema and data. Syntax pg_dump įor more options, you can use the following command: /pg_dump bin]$ bin]$. The dumps taken by pg_dump are totally consistent, because the dump is a snapshot of your database and its data at the time when the pg_dump begins running. It does not require any special privilege even a normal user can run it provided that user has permission on that particular database. The pg_dump runs when the server is up and running without blocking any reading or writing activity on the servers. The pg_dump utility takes a SQL script backup of a single database from your database cluster. In this article, we are going to cover the types of backups in PostgreSQL that we can use to load a sample database with schemas and data. This article discusses how to make a backup of a database using pg_dump in PostgreSQL and provides examples of how to make and restore the backups in different formats. ![]()
